This is good to know. I have seen some very old rotary cutters still in operation, so I guess I may just be over-thinking this. Thank you!I am on tractorbynet a bit and I've never heard of anyone actually wearing out a gearbox? Usually they break an input or output shaft or a gear in the first decade, or lose a seal and then people pump them full of corn head grease and carry on.
I got a chinese one and changed the oil to 85W140 and its been good for a decade now, and have broken a half dozen sheer pins, and even loaned it to my neighbor, and they tried to kill it but only bent the blades a little...
I am actually using Lucas hub oil, which is a 250w gear oil. Seems to be working fine!Why not? At this point I believe most of the gear lube reservoirs on my tractor and implements have been filled with Morey’s Oil Stabilizer as it’s thick enough to not leak out and I inherited a bunch of it.
My main concern would be long term and/ or unnecessary stress on the seals. Say it heats up and expands too fast or is simply too thick and the breather can’t keep up. I don’t know…I am actually using Lucas hub oil, which is a 250w gear oil. Seems to be working fine!
After it starts leaking00 grease?
Use what is recommended or higher and the gear box will last or it won't . Changing the oil is the best thing that can be done.This is good to know. I have seen some very old rotary cutters still in operation, so I guess I may just be over-thinking this. Thank you!
